This was purchased to replace a probe on my Aqua Controller Jr. It calibrated very easily and seems to be working well.

I use this product to turn on and off my two heaters in my 18o gallon reef tank. I am very satisfied with its performance. I wish the end cap were not so fat. Does not fit in all holders unless I feed it from the back end. Aside from that no issues.

After a little over a year, the probe which came with my Apex began showing large temp swings. I replaced the heater and there was no change so it had to be the probe. I ordered the replacement above. No more erratic readings! This probe is well built. The cord is very long which I needed!

I'm very pleased with this probe and it is definitely build to handle the harsh saltwater. I've been using Neptune temp probes for years and I've never had one fail.

Have 2 of these both read within .2 of eachother at all times. Get a .4 higher reading than using the coralife cheapos which is strange but I know that the Neptune ones are accurate and well made.

I have three of these units actively running. I calibrated each one via the web interface with a NIST-Traceable Temperature Probe. This neptune probe is made well, and all three have maintained their accurate values for well over a year of use so far. All three are submerged.
